Installation This section provides unpacking and installation instructions, and a description of external connections and backward alarm information. 2.1 Installation Requirements The Modem is designed to be installed within any standard 19-inch (48.26 cm) wide equipment cabinet or rack. It requires one rack unit (RU) of mounting space (1.75 inches/4.45 cm) vertically and 19.25 inches (48.89 cm) of depth. Including cabling, a minimum of 19.5 inches (49.53 cm) of rack depth is required. The rear panel of the modem is has power entering from the left and IF Cabling entering from the right (as viewed from the rear of the unit). Data and Control Cabling can enter from either side. The modem can be placed on a table or suitable surface if required. PROPER GROUNDING PROTECTION: During installation and setup, the user must ensure that the unit is properly grounded. The equipment shall be connected to the protective earth connection through the end use protective earth protection. In addition, the IF input and output coax cable shielding must be properly terminated to the Chassis/unit ground There are no user-serviceable parts or configuration settings located inside the Chassis. There is a potential shock hazard internally at the power supply module. DO NOT open the Chassis under any circumstances. 2-1 Universal Satellite Modem Installation Revision 2 Before initially applying power to the unit, it is a good idea to disconnect the transmit output from the operating ground station equipment. This is especially true if the current configuration settings are unknown, where incorrect settings could disrupt existing communications traffic. The modem contains a Lithium Battery. DANGER OF EXPLOSION exists if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries in accordance with local and national regulations. 2.2 Unpacking The Universal Satellite Modem was carefully packaged to avoid damage and should arrive complete with the following items for proper installation: 2.3 Modem Unit Power Cord, with applicable AC Connector Installation and Operation Manual Removal and Assembly The Modem is shipped fully assembled. It does not require removal of the covers for any purpose in installation. Always ensure that power is removed from the before removing or installing any optional modules. Failure to do so may cause damage to the equipment. Carefully unpack the unit and ensure that all of the above items are in the carton. If the available AC mains power at the installation site requires a different cordset from the one included in the package, then a suitable and approved cordset (for the country where the equipment is to be installed) will be required before proceeding with the installation. 2-2 Universal Satellite Modem Installation Revision 2 Should the Power Cable/AC Connector be of the wrong type for the installation, either the cable or the power connector end should be replaced. The power supply itself is designed for universal AC application. See specifications for appropriate voltages and currents. 2.4 Mounting Considerations When mounted in an equipment rack, adequate ventilation must be provided. The ambient temperature in the rack should preferably be between 10° and 35°C, and held constant for best equipment operation. The air available to the rack should be clean and relatively dry. The modems may be stacked one on top of the other to a maximum of 10 consecutive units before providing one (1) RU of space for airflow. Modems should not be placed immediately above a high-heat or EMF Generator to ensure the output signal integrity and proper receive operation. Do not mount the in an unprotected outdoor location where there is direct contact with rain, snow, wind or sun. The only tools required for rack mounting are four (4) customer supplied rack-mounting screws and the appropriate screwdriver. Rack mounting brackets are an integral part of the front bezel of the unit and are not removable. 2.5 Initial Configuration Check The modem is shipped from the factory with preset factory defaults. Upon initial power-up, a user check should be performed to verify the shipped modem configuration. Refer to Chapter 4, User Interfaces to locate and verify that the following configuration settings are correct: The Interface Type (V.35, RS-422, RS-232, G.703, etc.) MUST be selected from the Front Panel BEFORE the mating connectors are installed. Failure to do so may cause damage to the Universal Interface Module. Power up the modem, select the appropriate interface type, and then install the mating connectors. Transmit (Tx) and Receive (Rx) Interface types are dependent upon the customer’s order. 2-3 Universal Satellite Modem Installation Revision 2 Implementing Strap Code 26 can set the following modem configuration. Refer to Appendix D for an explanation and tabular listing of available Strap Codes. The Frequency and Modulator Output Power are set independently of the strap code. Standard Factory Configuration Settings Modulator: Data Rate: Mode: Satellite Framing: Scrambler: Drop and Insert: Inner FEC: Outer FEC: Modulation: Frequency: Modulator Output Power: 2.048 Mbps Closed Network None V.35 (IESS) Disabled 1/2 Rate Viterbi Disabled QPSK 70.000000 MHz -20 dBm Demodulator: Data Rate: Mode: Satellite Framing: Scrambler: Drop and Insert: Inner FEC: Outer FEC: Modulation: Frequency: 2.048 Mbps Closed Network None V.35 (IESS) Disabled 1/2 Rate Viterbi Disabled QPSK 70.000000 MHz To lock up the modem, enter ‘IF Loopback Enable’ under the Test Menu, or connect a Loopback Cable from J11 to J13 on the rear panel of the modem. Usage of the modems loopback capabilities in conjunction with the Ethernet data interface can produce undersirable network loops. In order to run any type of data test with an Ethernet interface you must utilize two modems connected back to back. Simply using one modem and a loopback will not produce the desired results. 2-4 Universal Satellite Modem Installation 2.6 Revision 2 Modulator Checkout The following descriptions assume that the modem is installed in a suitable location with prime AC power and supporting equipment available. 2.6.1 Initial Power-Up Before initial power up of the modem, it is a good idea to disconnect the transmit output from the operating ground station equipment. This is especially true if the current Modulator Configuration Settings are unknown, where incorrect settings could disrupt the existing communications traffic. New units from the factory are normally shipped in a default configuration which includes setting the transmit carrier off. Turn on the unit by placing the Rear Panel Switch (located above the power entry connector) to the On Position. Upon initial and subsequent power-ups, the Microprocessor will test itself and several of its components before beginning its Main Monitor/Control Program. These power-up diagnostics show no results if successful. If a failure is detected, the Fault LED will illuminate. The initial field checkout of the modem can be accomplished from the Front Panel or in the Terminal Mode. The Terminal Mode has the advantage of providing full screen access to all of the modem’s parameters, but requires a separate terminal or computer running a Terminal Program. The Terminal Mode is enabled from the front panel in the System M&C Submenus. 2.6.2 Factory Terminal Setup The factory terminal setup is as follows: Emulation Type: VT-100 (can be changed) Baud Rate: 19.2 K (Can be changed via Front Panel) Data Bits: 8 Parity: No Parity (Fixed) Stop Bits: 1 Stop Bit 2.7 Storage It is recommended that the unit be stored in its original sealed packing. The unit should be stored in a dry location where the temperature is stable, away from direct contact with rain, snow, wind, sun, or anything that may cause damage. 2-5 Universal Satellite Modem Installation Revision 2 Notes: 2-6 Chapter 3. Theory of Operation 3.1 Modem Hardware The modem is based on a two printed circuit card (minimum configuration) design with additional optioned printed circuit cards available for additional features. The minimum configuration consists of an L-Band/IF Assembly and a Digital Baseband Assembly. The optional printed circuit cards include a Turbo Codec printed circuit card and one of several types of Interface printed circuit card (refer to Appendix A). A block diagram of the DMD50 is shown in Figure 3-1. Figure 3-1. Block Diagram 3.1.1 L-Band/IF Printed Circuit Card The L-Band/IF Printed Circuit Card consists of an analog modulation function, an analog complex downconversion, and two wide-band digital synthesizers. The block diagram of the L-Band/IF Assembly is shown in Figure 3-2. In the modulator, analog in-phase (I) and quadrature (Q) signals are generated on the Digital Baseband Printed Circuit Card, routed to the L-Band/IF Printed Circuit Card, and modulated at the desired frequency. The L-Band 3-1 Universal Satellite Modem Theory of Operation Revision 2 or 70/140 modulated signal is then passed through a microprocessor controlled variable attenuator providing gain control of the output signal. In the complex downconverter, the signal for demodulation is amplified and sent through a variable wideband attenuator for AGC. The gain-controlled signal is then passed through a complex downconverter to a low IF. Figure 3-2. IF Card Block Diagram 3.1.2 Baseband Processing Printed Circuit Card The advent of million-plus gate count FPGAs, advanced logic synthesis tools, and DSPs providing hundreds of MIPs enabled the design of a software configurable modem. Large, fast FPGAs now provide designers with what is essentially an on the fly programmable ASIC. High speed, complex digital logic functions that previously could only be implemented in dedicated integrated circuits are now downloaded from a micro-controller through a serial or peripheral interface. When a new digital logic function is needed, a new configuration file is loaded into the FPGA. There is no limit to the number of digital logic configurations available to the FPGA, aside from the amount of Flash memory available to the system microprocessor for storage of configuration files. The Baseband Processing Printed Circuit Card provides a flexible architecture that allows many different modes of terrestrial and satellite framing, various FEC options, digital voice processing, and several different modulation/demodulation formats. Also included on the Baseband Printed Circuit Card are three synchronous interfaces, an EIA-530 Interface supporting RS-422, V.35, and RS-232. All three interfaces are provided on the same DB-25 Connector, and are selectable from the front panel. The Baseband Printed Circuit Card also contains the Monitor and Control (M&C) Circuitry responsible for: Programmable part setup and initialization Continuous control and adjustment of some functions Calibration Monitoring fault status Calculating and displaying measurements 3-2 Universal Satellite Modem Theory of Operation Revision 2 User monitor and control interface including front panel and remote Units configuration and feature set The M&C System is based on a powerful microprocessor with a large amount of Flash memory. several bus architectures are used to interconnect the M&C to all components of the DMD50. Communication to the outside world is done via connections to the remote port, terminal port, Ethernet port, and alarm ports. The M&C runs off of software programmed into its Flash memory. the memory can be reprogrammed via the Ethernet port to facilitate changes in software. 3.1.3 Enhanced Interface Printed Circuit Card The normal terrestrial data for the Baseband Processing Card can be re-routed to the enhanced interface card. The enhanced interface card adds a variety of connections to the modem for additional applications 3.2 Functional Block Diagram Figure 3-3 represents the Functional Blocks. The modem is shown in a typical application with customer data, Tx/Rx RF equipment and an antenna. Figure 3-3. Universal Satellite Modem Functional Block Diagram 3-3 Universal Satellite Modem Theory of Operation 3.2.1 Revision 2 Front Panel The Front Panel includes a 2 x 16 backlit LCD Display, Indicator LEDs, and a Numeric Keypad (refer to Chapter 4). 3.2.2 Baseband Processing The Baseband Processor performs all of the functions required for an IBS/IDR Framing Unit, a Reed-Solomon Codec, and an E1/T1 Drop and Insert System. In addition, the Baseband Processing Section provides for transmit clock selection and rate adaptation as well as a rate adapter and Plesiochronous/Doppler (PD) Buffer in the receive direction. A multiplexer is also provided for the SCT Clock Source for Loop Timing Applications. The transmit and receive paths may be configured independently under processor control. 3.2.3 Tx Baseband Processing The Tx Data and Clock enters the Baseband Processor, passes through a Rate Adapting FIFO and enters the Framer/Drop Processor. In IDR, IBS, and D&I Modes, the framer adds the appropriate framing and ESC as defined in IESS-308 and 309. In D&I Mode, the framer acquires the terrestrial framing structure, E1 or T1, and synchronizes the Drop Processor. The Drop Processor extracts the desired time slots from the terrestrial data stream and feeds these channels back to the framer. The framer then places the ‘dropped’ terrestrial time slots into the desired satellite channel slots. The data is then sent to the Reed-Solomon Encoder. When enabled, the Reed-Solomon Encoder, encodes the data into Reed-Solomon Blocks. The blocks are then interleaved and synchronized to the frame pattern as defined by the selected specification (IESS-308, IESS-309, DVB, etc.). After Reed-Solomon Encoding, the composite data and clock are applied to the BB Loopback Circuit. 3.2.4 Rx Baseband Processing The Receive Processor performs the inverse function of the Tx Processor. Data received from the satellite passes through the BB Loopback Circuit to the Reed-Solomon Decoder to the Deframer. The Deframer acquires the IBS/IDR/DVB frame, synchronizes the Reed-Solomon Decoder and extracts the received data and overhead from the frame structure, placing the data into the PD Buffer, sending the overhead data to the UIM. The data is extracted from the buffer and is sent to the UIM. Backward Alarm indications are sent to the M&C Subsystem. In Drop and Insert Mode, the Insert Processor synchronizes to the incoming terrestrial T1/E1 Data Stream, extracts satellite channels from the PD Buffer, and then inserts them into the desired terrestrial time slots in the T1/E1 Data Stream. 3.3 Monitor & Control (M&C) Subsystem The modems M&C system is connected to most of the circuitry on any board contained in the modem. These connections provide status on the working condition of the circuitry as well as providing the data required for the various measurements the modem provides. The M&C processes this information and generates status indications as well as alarms when necessary. Detailed status information is available via the modems various user interfaces including the remote and terminal ports. An external summary fault is available on the RS422 Data interface The M&C contains a high-performance microprocessor and is responsible for overall command and control of modem functions. The M&C is constantly monitoring all subsystems of the modem by performing a periodic poll routine and configures the modem by responding to commands input to the system. During each poll cycle, the status of each of the subsystems is collected and reported to each of the external ports. Performance statistics such as Eb/No, buffer fill %, etc. are compiled. If faults are detected, the M&C will take appropriate actions to minimize the effect of such faults on the system (refer to the Fault Matrices in Chapter 6). 3-4 Universal Satellite Modem Theory of Operation Revision 2 The modem supports the following M&C protocols: 3.3.1 Terminal Interface (Section 3.2.1) Remote Port Interface (Section 3.2.2) Ethernet M&C, Web Browser & SNMP (Section 3.2.3) Modem Status, Alarms & Contact Closures (Section 3.2.4) Terminal Port This port supports an asynchronous control protocol as described in Section 4. It is configured to support RS-232 signal levels. This port is intended for use in computer-based remote M&C. All functions of the modem may be monitored and controlled from this port via a common terminal connected to the Terminal Port. This function is front panel selectable. The Terminal Mode Control allows the use of an external terminal or computer to monitor and control the modem from a full screen interactive presentation operated by the modem itself. No external software is required other than VT-100 Terminal Emulation Software (e.g. “Procomm” for a computer when used as a terminal. The Control Port is normally used as an RS–232 Connection to the terminal device. The RS-232 operating parameters can be set using the modem Front Panel and stored in Non-volatile memory for future use. Refer to the Remote Protocol Manual (TM117) for the Terminal, Remote and SNMP screens and protocols. 3.3.2 Modem Remote Communications (RLLP) The Remote Port located on J20 allows for control and monitoring of parameters and functions via an RS-232 Serial Interface, or RS-485 for RLLP Protocol. ‘Equipment Remote Mode’ setup can be entered from the front panel or the Web Browser interface under the “System” menu. This requires the user to first set the Remote Port Control to “Remote” then set the Multidrop Address as needed followed by setting the Remote Interface to RS232 or RS485. Control and status messages are conveyed between the modem and all subsidiary modems and the host computer using packetized message blocks in accordance with a proprietary communications specification. This communication is handled by the Radyne Link Level Protocol (RLLP), which serves as a protocol ‘wrapper’ for the RM&C data. Complete information on monitor and control software is contained in the following sections. 3.3.3 Ethernet M&C Port This port is dedicated for Ethernet Communications supporting SNMP, FTP and Web Browser. The port is configured for 10 Base-T communications protocols. The Ethernet M&C Interface requires a standard RJ45 Male connector. Refer to Appendix D and F for proper setup of the TCP-IP interface and Web Browser Setup. 3-5 Universal Satellite Modem Theory of Operation 3.3.4 Revision 2 Modem Monitor Status The modems M&C system is connected to most of the circuitry on any board contained in the chassis. These connections provide status on the working condition of the circuitry as well as providing the data required for the various measurements the modem provides. The M&C processes this information and generates status indications as well as alarms when necessary. Detailed status information is available via the modems various user interfaces (front panel, remote and terminal). A summary of this information can be connected to external equipment, switches or alarms via the open collector and/or form-C fault connections Form-C Contacts: The UIM provides three Form-C Relays under processor control that appear at J15. Mod Fault: De-energized when any transmit side fault is detected. Demod Fault: De-energized when any receive side fault is detected. Common Fault: De-energized when any fault that is not explicitly a Tx or Rx Fault such as an M&C or Power Supply Fault. Open Collector Faults: The UIM provides two Open Collector Faults that appear at Pins 18 & 21 on J19. Mod Fault: Will sink up to 20 ma (maximum) until a transmit or common fault is detected. Will not sink current if a fault is detected. Demod Fault: Will sink up to 20 ma (maximum) until a receive or common fault is detected. Will not sink current if a fault is detected. The open collector faults are intended for use in redundancy switch applications in order to provide quick status indications. 3.4 Async Port / ES-ES Communications This port is dedicated for ES-ES Communications supported by either RS232 or RS485 signal levels. The baud rate and protocol can be selected from the Front Panel. The port may be configured for a number of communications protocols. Overhead data to/from the UIM is routed to/from the framer/deframer. This port is also used by SCC Framing for the in-band data. 3.5 Internal Clock The time and date is kept in order to ‘time-tag’ system events. User can change the Internal Clock via the front panel, Web Browser or Terminal ports. 3-6 Universal Satellite Modem Theory of Operation 3.6 Revision 2 Loopback Features (Terrestrial & IF) The modem provides for a number of different loopbacks. The Loopback supported are: IF Loopback – Tx IF port is looped back to the Rx IF port TX Terrestrial Loopback - Tx Data port is looped back to the Rx Data port after the interface driver/receiver. (prior to the framing unit) TX Baseband Loopback - Tx Data port is looped back to the Rx Data port after the interface driver/receiver. (after the fraiming unit) RX Terrestrail Loopback - Receive Data from the satellite is looped back for retransmission to the satellite, providing a far end loopback. (prior to the framing unit) RX Baseband Loopback - Receive Data from the satellite is looped back for retransmission to the satellite, providing a far end loopback. (after to framing unit) TX/RX Terrestrial Loopback - provides both Terrestrail loopbacks simultaneously TX/RX Baseband Loopback - provides both Baseband loopbacks simultaneously Usage of the modems loopback capabilities in conjunction with the Ethernet data interface can produce undersirable network loops. In order to run any type of data test with an Ethernet interface you must utilize two modems connected back to back. Simply using one modem and a loopback will not produce the desired results. 3-7 Universal Satellite Modem Theory of Operation Revision 2 Figure 3-4.

The various clocking options allow users to determine which clock will best fit their applications.

Clocking and Polarity Diagram 3.7.1 TX Clock Options TX clock options can be recovered from the terrestrial interface, satellite interface or internally generated. The allows users to select SCTE Clock (Terrestrial) or the SCT internal clock. The modem also allows user to recover the SCT Clock from the satellite (SCR) or from the modem internally. The modem allows users to select clock polarity. The Tx clock selections available are: 3-10 Universal Satellite Modem Theory of Operation Revision 2 The following paragraphs define the types of clocking options available to the user at the Front Panel. 3.7.1.1 SCT (Internal Oscillator) SCTE (External Tx Terrestrial Clock) Rx Satellite Clock SCTE: Serial Clock Transmit External The SCTE clock is the Transmit Terrestrial Clock associated with the data interface. SCTE is an external clock received from the terrestrial equipment and the modem utilizes the terrestrial clock to lock the internal clock. In Figure 3-9, the Transmit Terrestrial Data enters the modem and is clocked into a dejitter FIFO. Data is clocked out of the FIFO by the Modulator Clock. The Modulator Clock and Phase-Locked Loop (PLL), in conjunction with the Dejitter FIFO, which reduces the input jitter. Jitter reduction exceeds the jitter transfer specified in CCITT G.821. SCTE is sometimes referred to as Tx Terrestrial Timing or Terminal Timing. Terminal Timing is reference to the RS422 synchronous interfaces. 3.7.1.2 SCT: Serial Clock Transmit The SCT clock can be generated internally or recovered from the satellite. The SCT clock source can be used as the TX clock source, RX Buffer Clock source and the Terrestrial Terminal equipment for clocking the transmit data. If the SCT clock is recovered from the satellite, then it is referred to as SCR. SCR is also referred to as Receive Clock, Satellite Clock, or Receive Timing (RT). When SCT clock is configured as Internal, the frequency of the clock is set the same as the Transmit Terrestrial Clock rate. If SCT clock is configured as SCR, the internal clock is set to the same rate as the incoming receive satellite clock. SCT is sometimes referred to as Internal Timing or Send Timing (ST). In the event that the satellite clock is lost, the modem will automatically switch over to the Internal Clock and revert back to SCR when activity is detected. If SCT is selected, then Terrestrial data that is synchronous to the SCT Clock is required to be supplied by the modem. It is intended for the terminal equipment to use the SCT as its clock source. The Autophase Circuit will automatically ensure that the data is clocked correctly into the modem. Therefore, a return clock is not necessary. The Clock Polarity should be set to Auto. 3.7.2 RX Buffer Clock Options The modem supports a number of RX Buffer clock options that can be recovered from the satellite, terrestrial links, internally or externally. The various clocking options allow users to determine which clock will best fit their applications. Figure 3-7 gives an overview on how the modem processes the various clocks for the Tx Clock and the Rx Buffer Clock. The modem allows users to select clock polarity Tx and Rx Clocks may be independently locked. The following RX Buffer clock selections are available: Rx Satellite Clock (Recovered from Satellite) SCTE (External Tx Terrestrial Clock) SCT (Internal Oscillator) EXC Clock/EXT BNC (External Clock Source) EXT IDI (Drop and Insert) The modem handles RX Buffer clock selections based on source priority levels. The user assigns priorities to the clock sources based on source selections. Source 1 has the highest priority and Source 5 being the last resort or lowest priority. If a fallback clock is selected and activity is lost at the highest priority source, the modem will fall 3-11 Universal Satellite Modem Theory of Operation Revision 2 back to the next highest priority clock with activity. When activity resumes on a higher priority source, the modem resumes using the higher priority source Clock Source RX SAT SCTE SCT EXC BNC EXT IDI 1 2 3 4 5 Priority of of of of of 5 5 5 5 5 Refer to Front panel setup menus or Web Browser manual TM117. 3.7.2.1 RX SAT Clock The RX Sat clock is recovered from the satellite that is received from the distant end. If selected the Buffer Clock is lock to the RX sat clock. 3.7.2.2 SCTE: Serial Clock Transmit External When SCTE is selected as the Rx Buffer clock, the modem receives the clock from the Transmit Terrestrial interface. 3.7.2.3 SCT: Serial Clock Transmit If SCT clock is selected as the RX Buffer clock source, then it should be configured for internal. SCT is sometimes referred to as Internal Timing or Send Timing (ST). 3.7.2.4 EXT CLK/EXT BNC: External Clock, J16 The External Clock that can be selected as the RX Buffer clock source. This is a 75ohm unbalanced BNC connector. This clock source is also identified as EXT BNC. The External Clock is often used as the station master clock. The RX Clock selection can be accessed in the INTERFACE/RX SETUP menu. The clock frequency, EXT FREQ can be selected, in the Interface/General Menu. Clock specification: Frequency: Level: 3.7.2.5 1 MHz to 20 MHz 0.3 Vp-p to 5 Vp-p (Sine or Square wave) EXT IDI: Insert Data In External IDI is used only for E1/T1 Drop and Insert applications. The available T1/E1 Frame Source selections are External, Internal, and IDI/DDO Loopback. The T1/E1 Frame Source selections can be accessed in the INTERFACE/RX SETUP menus. If Ext IDI is selected as the RX Buffer clock, then user must first specify T1/E1 Frame Source. External (RX Buffer Clock recovered from the data) Internal (RX Buffer Clock recoverd from the internal clock) IDI/DDO Loopback (RX Buffer Clock recoverd from the data and looped back) 3-12 Universal Satellite Modem Theory of Operation 3.7.3 Revision 2 EXT REF: External Reference, Top BNC Port, J10 This is not actually a clock, but does have some clocking implications. When the external reference is used, the master oscillator within the modem is locked to the external reference, and the internal accuracy and stability of the unit assumes that of the External Reference. Therefore, not only are the transmit frequencies locked to the external reference, but the modem’s internal SCT Oscillator is locked to the external reference as well. External reference port input is specified at .3Vpp to 5Vpp (Sine or Square wave) 3.8 RS530/422/V.35 Interface (Standard) Data must be clocked into the modem by either the SCTE or SCT Source. If SCTE is selected as the Tx Clock Source, then SCTE must be supplied to the modem on the EIA-530 port. The output of the dejitter buffer will be clocked with this source. SCT should be used if SCTE has excessive jitter. 3.8.1 G.703 Interface (Optional) If the G.703 Interface is selected, then the Tx Clock Source will default to SCTE and the Clock Polarity will default to Auto. Loop timing with a G.703 Interface or Asymmetrical Data Rates requires external equipment at the remote end that is capable of using the recovered RD Clock as source timing for (SCTE) SD. The modem will not manipulate the clock frequency. Therefore, the transmit and receive clock rates must be equal in order for the modem to perform loop timing. 3.8.2 HSSI Interface (Optional) If the HSSI Interface is selected, then the Tx Clock Source will default to SCTE and the Clock Polarity will default to Auto. 3.8.3 Ethernet Data Interface (Optional) If the Ethernet Data Interface is selected, then the Tx Clock Source will default to SCTE and the Clock Polarity will default to Normal. If the Ethernet Data Interface is selected, then the Buffer Clock will default to RxSat and the Buffer Clock Polarity will default to Normal. 3-13 Universal Satellite Modem Theory of Operation 3.9 Revision 2 Reed-Solomon Codec Refer to Figure 3-8, Figure 3-9, and Table 3-1. Utilizing a Reed-Solomon (R-S) Outer Codec concatenated with a Convolutional Inner Codec is an effective way to produce very low error rates even for poor signal-to-noise ratios while requiring only a small increase in transmission bandwidth. Typically, concatenating an R-S Codec requires an increase in transmission bandwidth of only 9 – 12% while producing a greater than 2 dB improvement in Eb/No. R-S is a block Codec where K data bytes are fed into the encoder which adds 2t = (N – K) check bytes to produce an N byte R-S block. The R-S decoder can then correct up to “t” erred bytes in the block. 3.9.1 Reed-Solomon Operation When the Reed-Solomon Codec is enabled, data is fed to the R-S Encoding Section where it is scrambled, formed into blocks, R-S encoded, and interleaved. Unique words are added so that the blocks can be reformed in the Receiving Modem (Refer to Figure 3-8 and Figure 3-9). Data is then sent to the modulator where it is convolutionally encoded, modulated and transmitted to the satellite. When the signal is received and demodulated by the Receiving Modem, it is fed to a Viterbi Decoder for the first layer of error correction. After error correction is performed by the Viterbi Decoder, the unique words are located and the data is deinterleaved and reformed into blocks. The R-S Decoder then corrects the leftover errors in each block. The data is then descrambled and output from the R-S Section. 3.9.2 Reed-Solomon Code Rate The R-S Code Rate is defined by (N, K) where N is the total R-S block size in bytes - data + check bytes - and K is the number of data bytes input into the R-S Encoder. The transmission rate expansion required by the R-S Codec is then defined by N/K. The modem automatically sets the correct R-S code rate for IDR/IBS open network operation in accordance with the data shown in Table 3-1. The modem allows the following N and K setting: (126, 112), (219, 201), (194, 178), (225, 205). Variable Reed-Solomon rates are available on the optional AS/5167 Super Card. Refer to Appendix A for further information. 3-14 Universal Satellite Modem Theory of Operation 3.9.3 Revision 2 Interleaving Iinterleaving depths of 4, 8, or 12 R-S blocks are allowed. This allows burst errors to be spread over multiple blocks in order to enhance the error correcting performance of the R-S Codec. For Intelsat Network Modes, the interleaving depth is automatically set to 4 for QPSK or BPSK, or 8 for 8PSK. In Closed Network Mode, the interleaver depth can be manually set to 4 or 8, and in DVB Network Mode, the interleaver depth is automatically set to 12. Figure 3-8.

Design objective. 3-15 Universal Satellite Modem Theory of Operation 3.10 Revision 2 Asynchronous Overhead Operation (Framing/Multiplexer Capability) The Asynchronous Framing/Multiplexer is capable of multiplexing a relatively low-speed overhead channel onto the terrestrial data stream resulting in a slightly higher combined or aggregate data rate through the modem. The overhead channel is recovered at the far end. This added channel is termed variously “An Overhead Channel”, ”Service Channel”, “Async Channel” or in IESS terminology an “ES to ES Data Channel.” The basic frame structure used by the multiplexer is that specified in the IESS-309 Standard, resulting in a 16/15 Aggregate ratio of overhead & data to data rates. For Regular Async: For Enhanced Async: (Standard IBS), the Baud Rate is approximately 1/2000 of the Data Rate listed in Table 3-3. (IBS Async.), the Baud Rate is selectable, but Data Rate is limited. The maximum Baud Rate is 19,200 bps for IBS Async. Two software-controlled modes are designed into the card to best utilize the available bits; “Standard IBS” and “IBS (Async)”. The characteristics of the Channel Interface is also determined by the standard or Async mode. The Async Channel can be set under software-control to either RS-232 or RS-485 mode. The pin assignments for both modes are shown in Table 5-3. The “RS-485” Setting controls the output into tri-state when the modem is not transmitting data, allowing multiple modem outputs to be connected together. Table 3-2.

The bits of Overhead Housekeeping byte 32 are implemented as shown in Table 3-3 below: Table 3-3. Bits of Overhead Housekeeping Bit 1 ES to ES Data Channel This bit is routed directly to the ES to ES Data Channel. Its data rate is 1/512th of the aggregate rate (or 1/480th of the through terrestrial data rate), and is normally used to super-sample an asynchronous data channel. Bit 2 Frame Alignment Part of the Frame Alignment word. Bit 3 Backward Alarm Transmit and Receive with main processor to activate Main Alarm/LED. Bit 4 Multiframe Message As per IBS. Bits 5 and 6 Spare Not currently utilized. Bits 7 and 8 Encryption Utilization Not currently utilized. The ratio of the Through Terrestrial Data Channel Rate to the aggregate rate is 15/16. The standard transmit and receive channels of the ES to ES Data Channel in Standard IBS Mode are raw channels operating at the specific bit rate as controlled by the data channel rate, without buffering. In addition, no clocks are provided with this channel. Since it would be rare that the data rate provided was exactly that required for a standard rate device, the only method of communicating using this channel is to allow it to super-sample the user data. 3-17 Universal Satellite Modem Theory of Operation 3.12 Revision 2 Asynchronous Multiplexer Mode Since many of the frame bits in the standard IBS mode are not used, an “Enhanced” Multiplexer Mode has been implemented that can be engaged under software control. Since this mode changes the use of many of the framed non-data bits, this mode is only usable when the DMD50 is at both ends of a link. In this mode, the overhead signaling bytes 16 and 48 can be used to implement a significantly higher speed ES to ES Data Channel under software control. When implemented, this rate is 16 times that of the normal IBS standard, or 1/30th of the terrestrial data rate (1/32nd of the aggregate rate). The IBS Async mode MUST be selected for true Asynchronous channel operation to be available. 3.13 ESC Backward Alarms When running in IDR Mode and if the modem has the ESC Option, there will be four Backward Alarms available for use by the earth stations at each end of the link (both ends must have the ESC option). These alarms are accessed via the ESC ALARMS Port. The four alarms are controlled by four relays, each having a normally open, normally closed, and a common connection. The common connections of these relays (referred to as Backward Alarm Inputs) can be connected to whichever system on the earth station that the user wishes to trigger the backward alarm. When ground is applied to the Common (Input) Connection of one of these relays, that relay and associated backward alarm will then be in a “no fault” state. When the ground is removed, the relay and the associated Tx Backward Alarm will toggle to the faulted state. When in the faulted state, the receive end of the link will receive that backward alarm that is initiated at the transmit end of the link. The user can connect whichever systems on the earth stations that they desire to these Backward Alarms Relays as long as they will supply ground to the Backward Alarm Relay Input in the “no fault” condition and the ground will be removed in the “faulted” condition. For example: the user could connect the Demod Summary Fault of the modem to the Backward Alarm 1 Input, so that if the demod went into Major Alarm (such as a Carrier Loss), Backward Alarm 1 would be transmitted to the receive end of the link. At the receive end, it would show up as Rx Backward 1 (Receive Backward Alarm 1). 3.13.1 To Disable the ESC Backward Alarms If the ESC ALARMS Port will not be used and the Backward Alarm Indications are to be disabled, you must connect pins 10, 11, 22 and 23 to pin 1 (gnd) on ESC Alarms port. 3-18 Universal Satellite Modem Theory of Operation 3.14 Revision 2 Satellite Control Channel (SCC) The SCC format uses a variable overhead rate to transmit an asynchronous data channel in addition to the normal data channel. The SCC asynchronous mode implemented on the DMD50 is "PassThru" Mode. 3.14.1 SCC Framing Structure Each SCC frame consists of the following: A 10-bit synchronization pattern called the Synchronizing Word. Multiple variable length slots filled with user data. Multiple 10-bit control words that contains eight bits of in-band data (the extra two bits are for the async start/stop). The number of user data slots and control words per frame is selected by the SCC Control Ratio Parameter. This can be any value from 1 to 1 through 1 to 7. A higher ratio allows a lower overhead rate but since there are less Sync Words, there is a higher acquisition time. The following examples show a control ratio of 1 to 3 and 1 to 1. Example 1 shows three Control Words for every Synchronizing Word, and Example 2 shows one Control Word for every Synchronizing Word. 1 to 3 Control Ratio 1 to 1 Control Ratio The Control Ratio of the receiving units must match the Control Ratio of the transmitting unit. 3-19 Universal Satellite Modem Theory of Operation 3.14.2 Revision 2 Aggregate Data Rate The aggregate data rate equals the following: User Data Rate + In-Band Rate + Synchronizing Overhead Rate Because SCC must adjust the overhead so that there are an equal number of user data bits in each slot, the synchronizing overhead cannot be easily calculated. However, dividing the In-Band Rate by the Control Ratio can approximate it. The following equation shows the basic calculation of this rate: Aggregate Date Rate = User Data Rate + In-Band Rate + (In-Band Rate/Control Ratio) In-Band Rate User Data Rate Synchronizing Overhead Aggregate Data Rate As an example, given the following parameters: User Data Rate: In-Band Rate: Control Ratio: 1,024,000 bps 19,200 bps 1 to 7 Aggregate data rate = 1,024,000 + 19,200 + (19,200/7) or approximately 1,045,942 (actually 1045974). This gives an overhead ratio of 1,045,974/1,024,000 = 1.021 In addition, another constraint changes the actual Aggregate Data Rate. The user data slot size is limited to 2,500 bits. Because of this, the modem increases the in-band rate to reduce the user data slot size. This only happens at higher user data rates. 3.14.3 Overhead Rate Comparison The SCC Overhead Ratio varies depending on the User Data Rate, the In-Band Rate, and the Control Ratio. This gives SCC the advantage of lower overhead rates when compared to IBS, which has a fixed overhead ratio of 16/15 or 1.067. Table 3-4 shows example overhead rates for different user data and control ratios. Table 3-4. Overhead Rates Examples User Data Rate 512,000 1,024,000 2,048,000 3,072,000 4,096,000 6,312,000 6,312,000 6,312,000 In-Band Rate 19,200 19,200 19,200 19,200 19,200 19,200 19,200 19,200 Control Ratio 1/7 1/7 1/7 1/7 1/7 1/7 1/3 1/1 3-20 Aggregate Data Rate 533,974 1,045,974 2,069,951 3,093,943 4,117,951 6,337,248 6,337,606 6,350,418 Overhead Ratio 1.043 1.021 1.011 1.007 1.005 1.004 1.004 1.006 Universal Satellite Modem Theory of Operation 3.14.4 Revision 2 Actual Overhead Rate Calculation The following is the actual calculation the modem does to calculate the overhead ratio: 1. The modem calculates the minimum in-band rate to limit the size of the user data slots to 2,500 bits (the result is truncated to an integer). Minimum In-Band = (User Data Rate * Control Ratio)/((Control Ratio + 1) * 250) 2. Using the bigger of Minimum In-Band or the selected In-Band, the modem calculates the number of bits for each user data slot (result is truncated to an integer). Slot Bits = (User Data Rate * (Control Ratio * 10))/(In-band Rate * (Control Ratio + 1)) The actual ratio the modem uses is: Actual Ratio = (Slot Bits + 10)/Slot Bits Example 2: Example 1: User Data Rate: 1,024,000 bps User Data Rate: 6,312,000 bps In-Band Rate: 19,200 bps In-Band Rate: 19,200 bps Control Ratio: 1 to 7 Control Ratio: 1 to 7 Minimum In-Band = (1,024,000 * 7)/((7 + 1) * 250) = 3,584 (less than In-Band Rate) Minimum In-Band = (6,312,000 * 7)/((7 + 1) * 250) = 22,092 (more than In-Band Rate) Slot Bits = (1,024,000 * (7 * 10))/(19,200 * (7 + 1)) = 466 Slot Bits = (6,312,000 * (7 * 10))/(22,092 * (7 + 1)) = 2,500 Actual Ratio = (466 + 10)/466 = 1.021 3.14.5 1. Actual Ratio = (2,500+ 10)/2,500= 1.004 SCC Overhead Channel Setup Set the Framing Mode (located under Mod and Demod Data Menus) to SCC. After doing this, two new menus will appear to the right of the Framing Menu, for both the Mod and Demod. The new menus will be: SCC CTL RATIO SCC INBAND RATE 2. Set the desired SCC control ratio: SCC CTL RATIO {1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7} This allows the user to simulate the framing used by the Satellite Control Channel Option (PassThru Mode only). The SCC CTL RATIO is the ratio of overhead in-band data to synchronizing words. 3. Set the desired SCC in-band rate: SCC INBAND RATE {300 to 200000} 3-21 Universal Satellite Modem Theory of Operation Revision 2 This allows the user to request the rate of in-band data for the overhead channel. This sets the overhead amount only. The actual amount of data that can be passed through the overhead channel will be set under “ES Baud Rate” (see Step 6 below). 4. Under the Interface > General menus, locate the TX ASYNC MODE (menu). 5. Under the TX ASYNC MODE Menu, set the desired ES Interface type: ES INTERFACE {RS-232, RS-485} This allows the user to select the interface type. 6. Under TX ASYNC MODE Menu, set the desired baud rate for the ASYNC Port (J17). This will be the baud rate that will pass through the overhead channel: ES BAUD RATE {150 - 19200} This allows the user to select the baud rate of the ASYNC port (J17) in SCC Mode. 7. Under TX ASYNC MODE Menu, set the desired ES BITS/CHAR: ES BITS/CHAR {7,8} This allows the user to choose between 7 or 8 bits of data. 3.15 8. Repeat Steps 4 through 7 under the RX ASYNC MODE (menu) 9. The physical connection to the overhead channel will be the DB-9 Female Port labeled ASYNC (J17). EDMAC Satellite Framing/Deframing Mode The modem supports EDMAC satellite framing. EDMAC can be enables for both modulator and demodulator satellite framing when modem is configured in CLOSED NET applications. EDMAC satellite framing DOES NOT allow control or monitoring of the remote slave modem. On the demodulator, terrestrial date is framed with NULL EDMAC commands, having no effect at the remote demodulator. On the demodulator, EDMAC commands are stripped from the satellite data stream and discarded, leaving the terrestrial data steam intact. EDMAC Framing/Deframing is provided for compatibility purposes only. 3.16 Locating the ID Code Operational Procedure The modem has unique ID codes that allow the user to add feature upgrades to the modem without the unit having to be returned to the factory. Users are required to identify these ID codes when they want additional features added to their unit. Comtech will supply a new ID code that is required to be entered in the ID code field. Once the new ID code is entered, the modem will activate the new features. Refer to Appendix B for upgrade procedures. 3.17 Strap Codes The Strap Code is a quick set key that sets many of the modem parameters. For quick setup of the modem, Strap Codes are very helpful. When a Strap Code is entered, the modem is automatically configured for the 3-22 Universal Satellite Modem Theory of Operation Revision 2 code’s corresponding data rate, overhead, code rate, framing, scrambler type and modulation. An example of how to set a strap code follows: Example: In the Ethernet interface <Modulator> Menu, depress the Transmit Gel-tab, then move the cursor down and depress “General”. Now move the cursor over to ‘Strap Code’. Click inside the box and enter the new strap code submenu and enter #16. The DMD50 will be automatically configured to the parameters shown below in the highlighted row ‘Strap Code 16’. Refer to Appendix D or the various strap code options. 3-23 Universal Satellite Modem Theory of Operation Revision 2 Notes: 3-24 Chapter 4.

LOOPBACK WITH ETHERNET DATA INTERFACE Usage of the modems loopback capabilities in conjunction with the Ethernet data interface can produce undesirable network loops. In order to run any type of data test with an Ethernet interface you must utilize two modems connected back to back. Simply using one modem and a loopback will not produce the desired results. LOOPBACK {IF, TERR TX/RX, BASEBAND TX/RX, NONE, TERR RX, BASEBAND RX, TERR TX, BASEBAND TX, IFEC TX} Terrestrial Loopback is performed at the Terrestrial Interface IF: IF loopback loops the IF output of the Modulator to the IF input of the Demodulator. If using 8PSK or 16QAM Modulation, the output power must be above -15 dB. TERR TX/RX: Enables both. Baseband loopback is performed at interface between the Baseband Processor Card and the Modem Card. This ensures Framer/Deframer integrity. BASEBAND TX/RX: Enables both Baseband Tx and Baseband Rx. NONE: No loopback performed.

POS FIR: For manufacturer’s use only. NEG FIR: For manufacturer’s use only. 4.5 Terminal Mode Control The Terminal Mode Control allows the use of an external terminal or computer to monitor and control the modem from a full screen interactive presentation operated by the modem itself. No external software is required other than Terminal Emulation Software (e.g. “Procomm” for a computer when used as a terminal. The Control Port is normally used as an RS–232 Connection to the terminal device. The RS-232 operating parameters can be set using the modem Front Panel and stored in Non-Volatile Memory for future use (refer to Remote Protocol Manual for setup and terminal screens). Refer to Remote Protocol Manual for terminal screens. 4.5.1 Modem Terminal Mode Control The modem can be interactively monitored and controlled in the Terminal Mode, with a full screen presentation of current settings and status. The Terminal Control Mode supports several baud rates, however the connection must be set for 8 data bits, 1 stop bit and no parity (8,N,1). 4.5.2 Modem Setup for Terminal Mode Terminal Mode Communications and Protocol is set from the Front Panel Control by setting the “Control Mode” Parameter to “Terminal”, and then setting the “Modem Port”, “Term Baud” and “Emulation” Parameters as desired. Then a terminal is connected to Connector J20 on the Back Panel. All operating software for the Terminal Mode is contained within the Modem Internal Control Software. A “break” signal on the communications line, pressing “ESC” on the terminal or Power On of the modem will initiate full screen terminal mode printing and redraw the full screen. The Terminal Mode displays the present 4-37 Universal Satellite Modem User Interfaces Revision 2 status of all user parameters controlled and read by the processor, and offers a menu allowing change to any controlled parameter. The Terminal Mode uses eight “Screens,” each of which have the basic contents of the three modem monitor and control areas as set in the Front Panel matrix columns. This screen is used for setting the parameters of the Modulator, Demodulator, Event, Alarm, Latched Alarm, Drop Controls, Insert Controls, and Interface Areas. 4.6 Terminal Port User Interface The Remote Port (J20) of the modem allows for complete control and monitoring of all parameters and functions via an RS-232 Serial Interface. ‘Terminal Mode’ can be entered from the front panel by selecting “System” and then “Control Mode” followed by “Terminal”. The baud rate and evaluation type can be changed at the front panel by using the System>Baud Rate Menu. The Terminal Control Mode is menu-driven and the allowable values for each item number will be shown. To change an item, type in its number followed by <ENTER>. If the parameter to be changed requires a numeric value, enter the number followed by <ENTER> If the parameter is non-numeric, press <SPACE> to cycle through the list of available entries. Items that do not have ID numbers are Status only and cannot be changed. 4.7 Connecting the Terminal 1. Connect the computer to the Remote Connector (J20) on the rear of the unit using the RS-232 Cable. 2. Enable the terminal by selecting Terminal Mode (located under the System - Control Mode Menu) from the front panel. 3. Verify that your emulation software is set to the following: 8 data bits no parity 1 stop bit Modify the selection, if necessary, to match the settings (the Front Panel ‘SYSTEM’ Sub-Menu contains all the Terminal Emulation Controls). 4-38 Universal Satellite Modem User Interfaces 4.8 Revision 2 Terminal Screens For terminal screens, refer to the Remote Protocol Manual. 4.9 RS485 Remote Port Interface (RLLP Protocol) The Remote Port allows for complete control and monitoring of all parameters and functions via an RS-232 Serial Interface or RS-485 utilizing RLLP Protocol. ‘Equipment Remote Mode’ can be entered from the GUI interface under the “System” menu by selecting “System” and then “Terminal” followed by “Terminal”. The baud rate and evaluation type can be changed at the front panel by using the System>Baud Rate Menu. Control and status messages are conveyed between the modem and all subsidiary modems and the host computer using packetized message blocks in accordance with a proprietary communications specification. This communication is handled by the Radyne Link Level Protocol (RLLP), which serves as a protocol ‘wrapper’ for the RM&C data. Complete information on monitor and control software is contained in the following sections. 4.9.1 Protocol Structure The Communications Specification (COMMSPEC) defines the interaction of computer resident Monitor and Control Software used in satellite earth station equipment such as modems, redundancy switches, multiplexers, and other ancillary support gear. Communication is bi-directional, and is normally established on one or more fullduplex 9600-baud multi-drop control buses that conform to EIA Standard RS-485. Each piece of earth station equipment on a control bus has a unique physical address, which is assigned during station setup/configuration or prior to shipment. Valid decimal addresses on one control bus range from 032 through 255 supporting up to 224 devices per bus. Address 255 of each control bus is usually reserved for the M&C computer. 4-39 Universal Satellite Modem User Interfaces 4.10 Revision 2 Ethernet Remote Port Interface (SNMP & Web Browser) This port is dedicated for Ethernet Communications supporting SNMP, FTP and Web Browser. The port is configured for 10 Base-T communications protocols. The Ethernet M&C Interface requires a standard RJ45 Male connector.

Maintenance and Troubleshooting This section discusses unit maintenance and troubleshooting for the Universal Satellite Modem. The modem contains a Lithium Battery. DANGER OF EXPLOSION exists if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries in accordance with local and national regulations. 6.1 Periodic Maintenance There is no external fuse on the modem. The fuse is located on the power supply assembly inside the case, and replacement is not intended in the field. 6.1.1 Clock Adjustment The modem allows for VCO speed adjustment from the front panel. Clock adjustment should be performed only when an internal clock source has insufficient accuracy for the custom modem application. 6-1 Universal Satellite Modem Maintenance and Troubleshooting 6.2 Revision 2 Troubleshooting Should a unit be suspected of a defect in field operations after all interface signals are verified, the correct procedure is to replace the unit with another known working unit.

The alarms for these faults are separated into the following three categories: Active Alarms Common Equipment Alarms Backward Alarms A feature exists that allows the user to ‘Mask’ out certain alarms as explained below. Masking alarms may cause undesirable modem performance. When an alarm is masked, the Front Panel LEDs and the Fault Relays do not get asserted, but the Alarm will still be displayed. This feature is very helpful during debugging or to lock out a failure of which the user is already aware. 6.2.2.1 Active Alarms 6.2.2.1.1 Major Alarms Major Alarms indicate a modem hardware failure. Major Alarms may flash briefly during modem configuration changes and during power-up but should not stay illuminated. Alarms are grouped into Transmit and Receive Alarms - Transmit and Receive are completely independent. 6.2.2.1.2 Minor Alarms Minor Alarms indicate that a problem may persist outside the modem such as loss of Terrestrial Clock, loss of terrestrial data activity, or a detected transmit or receive AIS condition. Alarms are grouped into Transmit and Receive Alarms - Transmit and Receive are completely independent. 6.2.2.1.3 Common Equipment Faults Common equipment faults indicate hardware or configuration problems in the modem that effect both transmit and receive operation. Most common faults indicate a hardware failure within the modem, such as a bad power supply. Common faults for the External Reference and External Clock indicate a bad modem configuration, not a hardware failure. 6.2.2.2 Latched Alarms Latched Alarms are used to catch intermittent failures. If a fault occurs, the fault indication will be latched even if the alarm goes away. After the modem is configured and running, it is recommended that the Latched Alarms be cleared as a final step. 6-5 Universal Satellite Modem Maintenance and Troubleshooting 6.2.2.3 Revision 2 Backward Alarms Backward Alarms are alarms that are fed back to or received from the other end of the satellite link. In IBS Mode (including Drop & Insert), Backward Alarm 1 is the only one used. It would be received if the distant end demod drops lock. 6.3 IBS Fault Conditions and Actions Figure 6-1 and Table 6-1 illustrate the IBS Fault Conditions and Actions to be taken at the Earth Station, at the Terrestrial Data Stream, and the Satellite. These faults include those detected on the Terrestrial link and those detected from the satellite. Figure 6-1.

B-2 Universal Satellite Modem Front Panel Upgrade Procedure Revision 2 B.4 Demonstration Procedure The procedure for enabling a 30-day demo of the options is similar to the procedure used for permanently updating the modems feature set. The one big difference being that at the end of 30 days, the demo features will automatically be disabled and the modem will revert back to its permanent configuration. At the end of the demonstration period, when the modem reverts back to its permanent configuration an interrupt in traffic will occur, regardless of whether or not a demo enabled features was being run at the time. In addition, operator intervention may be required to restore the data paths. In order to avoid this interruption in service, the user can cancel the demonstration at any time by following the instructions outlined in the section on “Canceling Demonstration Mode.” 1.

Scroll right through the available list of options. The top line identifies the options and the second line identifies the options status. DEMO MODE indicates that the option is has been temporarily activated and is now available for evaluation as part of the modems feature set. At the end of the demonstration period, the modem will revert back to its permanent configuration. When it does, an interrupt in traffic will occur, regardless of whether or not a demo enabled features was being run at the time. In addition, operator intervention may be required to restore the data paths. In order to avoid this interruption in service, the user can cancel the demonstration at any time by following the instructions outlined in the section on Canceling Demonstration Mode. B-5 Universal Satellite Modem Front Panel Upgrade Procedure Revision 2 B.4.2 Canceling Demonstration Mode At any time, a demonstration may be canceled and have the modem return to its normal operation. Once the demonstration has been canceled, it cannot be restarted using the old demonstration code. In order to restart a demonstration, it will be necessary to obtain a new demonstration code. To cancel a demonstration from the front panel, perform the following: 1. 2. 3. 4. 5. 6. From the modem’s Main Menu, scroll right to the SYSTEM Menu. Scroll down. Scroll right to the HW/FW CONFIG Menu. Scroll down. Scroll right to the FEATURES Menu. Scroll down. The value displayed on the top line of this menu is the 12-digit Unit ID. It is displayed on the front panel of the modem as 3 sets of 4 digits in a dot-delineated format indicated in Parameter Setup, Chapter 4. The second line is the data entry area and is displayed as 3 sets of 4 underscores in a dot-delineated format. Press <ENTER> and a cursor will begin flashing in the data entry area Using the numeric keypad, enter 0000 0000 0000 Press <ENTER>. The modem will immediately terminate the demonstration and the feature set will revert back to the permanent configuration. The Mod and Demod Test LED's will stop flashing. B-6 Appendix C. Carrier Control C.1 States The transmitter will turn off the carrier output automatically when the modem determines there is a major alarm. This is done to prevent the carrier from outputting an unknown spectrum and possibly disturbing adjacent carriers. This automatic drop of the carrier can be overridden by masking the alarm that is causing the fault. This will keep the modulator output spectrum transmitting, even when the fault occurs. The following Carrier Control states are available: Carrier OFF Carrier ON Carrier AUTO Carrier VSAT Carrier RTS C.2 Carrier Off Modulator output is disabled. C.3 Carrier On Modulator output is turned off before reprogramming modulator functions that may alter the output spectrum through the front panel, and the user is required to enter “Yes” to re-enable output after the change. When using the terminal, the modulator is turned off while re-programming modulator functions that may alter the output spectrum, and the user is required to manually turn on the output after the reprogramming. C.4 Carrier Auto Modulator output is turned off before reprogramming modulator functions that may alter the output spectrum through the front panel, but the output is automatically turned on after the change. When using the terminal, the modulator is turned off while re-programming modulator functions that may alter the output spectrum, and but the output is automatically turned on after the change. C-1 Universal Satellite Modem Carrier Control Revision 2 C.5 Carrier VSat Modulator output is turned off before reprogramming modulator functions that may alter the output spectrum through the front panel, and the user is required to enter “Yes” to re-enable output after the change. When using the terminal, the modulator is turned off while re-programming modulator functions that may alter the output spectrum, and the user is required to manually turn on the output after the reprogramming (same as “Carrier On”). Additionally “VSat” mode disables the modulators output when the modems demodulator does not have signal lock. When signal lock returns to the demodulator, the modulator turns the carrier back on. C.6 Carrier RTS Modulator output is turned off before reprogramming modulator functions that may alter the output spectrum through the front panel, and the user is required to enter “Yes” to re-enable output after the change. When using the terminal, the modulator is turned off while re-programming modulator functions that may alter the output spectrum, and the user is required to manually turn on the output after the reprogramming (same as “Carrier On”). Additionally “RTS” (Request To Send) mode enables the modulator’s output based on the RTS lead of the data interface. When RTS is enabled on the data interface, the modulator turns on the carrier, when the RTS is disabled the modulator turns off the carrier. C-2 Appendix D. Strap Codes D.1 Strap Codes The Strap Code is a quick set key that sets many of the modem parameters. For quick setup of the modem, Strap Codes are very helpful. When a Strap Code is entered, the modem is automatically configured for the code’s corresponding data rate, overhead, code rate, framing, scrambler type and modulation. An example of how to set a strap code follows: Example: At the Front Panel <Modulator> Menu, depress ‘↓’, then move ‘→’ to the ‘Strap Code’ Submenu and enter #16. The modem will be automatically configured to the parameters shown below in the highlighted row ‘Strap Code 16’. Use the Strap Code Guide (Table D-1) for available strap codes. Table D-1.

TCP/IP Ethernet Setup E.1 Introduction The modem supports SNMP, FTP protocols and the Web Browser. Utilization of the protocols is dependent upon proper set up of the TCP-IP menus. This document is to be used only as a guideline for setting up the TCP-IP menus. Contact the IT manager for proper guidance to ensure setup is successful. For additional information on the various WEB or SNMP configurations and descriptions refer to the Remote Protocol Manual (TM117). E.2 TCP/IP Network Configuration Using the Front Panel display and arrow keys, scroll thru the System menu until the TCP / IP sub menu is displayed. Each unit requires proper configuration with the correct network settings. Contact the IT manager for a valid IP address mask, Modem, server and router IP addresses. Enter into the TCP / IP menu and the following Sub menus will appear, however the order may vary. 1. Boot Mode: This allows for the selection of the operating boot mode for the TCP / IP. Several selections are available and are described below. When configuring the modem for Web Browser, Boot Mode must be set to “NON-VOL”. A brief description of the available selections are: a. Default: If the Ethernet interface is not to be used, select this mode. No IP Address or mask changes will be allowed while in this mode of operation. The following parameters will be set and will not change until the boot mode is changed. The IP addresses are non accessible addresses. • • • • IP MASK MODEM IP ADDR SERVER IP ADDR ROUTER IP ADDR 255.000.000.000 010.000.000.001 010.001.001.001 010.000.001.001 b. BOOTp: When enabled, at boot time, the modem will use the Bootp Protocol to automatically get names, masks, and IP Addresses of the modem, router, and server from the Network Manager. This should be consistent with the tag expected by the users Bootp Server (see the next menu selection for setting the BOOTp TAG). If Bootp is not enabled, the modem will ignore the BOOTp Tag setting. c. NON-VOL: This will allow for setting up all required IP Addresses and will store the information to the non-volatile memory. Upon power cycle, the modem will restore the saved settings into the correct fields. E-1 Universal Satellite Modem TCP/IP Ethernet Setup Revision 2 d. IP TEST: The IP Test selection is similar in behavior to the Default selection. When enabled, the following preset parameters will be programmed and will not change until the selection is changed. To edit these parameters, change the boot mode to NON-VOL. IP MASK MODEM IP ADDR SERVER IP ADDR ROUTER IP ADDR 255.255.255.000 192.168.000.238 192.168.000.101 192.168.000.102 The modem is shipped from the factory with the Boot Mode configured as Default. Verify that the Boot Mode is set for Default. To access the unit via the Ethernet port, set the selection to IP TEST. This will set the IP parameter to an accessible address. If user wants to utilize an alternate address, user must set the selection to NON-VOL. As an example, we will use a new modem IP address of 172.018.100.205 for the remaining of the TCP-IP setup procedure. Contact the IT manager for proper guidance to ensure setup is successful. 2. BOOT SERVER TAG: This allows for the selection of the operating boot tag when operating in the BOOTp Mode. The default setting of 206 is automatically selected when the boot mode is set to ‘DEFAULT’ (factory preset mode). 3. MODEM HOST: This displays the unit Host name, this is a read only display. 4. IP ADDR MASK: This will allow for the entry of the IP Address Mask. This will need to be entered based on the Network settings. Refer to your IP Administrator if you do not know this address for the correct address setting. Example IP Address Mask setting: 255.255.000.000. 5. MODEM IP ADDR: This will allow for the entry of the Modem‘s individual network IP Address. Each device on the network will have a unique address. Refer to the IT administrator for the correct address setting. Example Modem IP Address setting: 172.018.100.215. 6. SERVER IP ADDR: This allows for the setup of the Network Server IP Address. This section refers to the Host that will be used to optionally boot the modem on power-up and is the SNMP Trap Server. This IP Address needs to be consistent with the Modem IP Address. Broadcast and loop back addresses will not be allowed. Example Server IP Address setting: 172.018.004.250. 7. ROUTER IP ADDR: This allows for the setup of the Network Router IP Address. If a router is present on the local network, and it is to be used, this address must be consistent with the IP Address Mask and the subnet of the modem. If no router is present, then the address should be set to a foreign address. Broadcast and loop back addresses will not be allowed. Router not used example: Router IP Address setting: 010.000.001.001. 8. MODEM EADDR: This displays the Modem (Unit) Ethernet Address. The Modem Ethernet Address is configured at the factory. It is a unique Radyne equipment identifier Address. Example: 0010650903EB 9. ETHER RATE: This displays the current Ethernet port data rate. If multiple rates are available, then a selection can be made to specify the Ethernet port data rate (10BaseT). Example Ethernet port Data Rate: 10 MBPS/HD E-2 Universal Satellite Modem TCP/IP Ethernet Setup Revision 2 E.3 Network Configuration Summary If the above steps were followed and the information was entered, then the following would be the TCP / IP configuration summary for a ‘no router specified’ setup: 1. 2. 3. 4. 5. 6. 7. 8. 9.

The Server and Modem are on the same subnet. E-6 Appendix F. Web Browser Setup Guide F.1 Introduction The Web Browser allows for connection to Radyne products through the Ethernet port. The Web interface allows for complete control and monitoring of all equipment parameters and functions via a 10Base-T Ethernet connection. Utilization of the Web browser is dependent upon proper set-up of the TCP-IP menus. For TCP-IP setup guidelines refer to Appendix G in the manual. For additional information on the various WEB configurations and descriptions refer to the Remote Protocol Manual TM117. Utilization of the Web Browser requires proper setup of the TCP-IP menus. The unit is shipped from the factory with the Boot Mode configured as Default. Verify that the Boot Mode is set for Default. To access the unit via the Ethernet port, set the Boot Mode to IP TEST. This will set the IP parameter to an accessible address. If user wants to utilize an alternate address, user must set the Boot Mode to NONVOL. Contact the IT manager for proper guidance to ensure setup is successful. F.2 WEB Users Configuration Radyne utilizes authentication and authorization together with a user database and a security realm to design a secure site. This allows for the use of users and groups, where users are generally people that may access the system, and groups represent the position that users can hold. The Modem’s Front Panel has full administrative privileges, allowing the operator through the Front Panel Menu entries to perform monitor and control modem parameter settings, change other interface user names and passwords, and modify IP network settings. F-1 Universal Satellite Modem Revision 2 AUPC Operation The web user database consists of three users (USER 1, USER 2, USER 3), with initial default names of guest, oper, and admin. Access rights and authentication make it possible to restrict access to a specified set of web users. There are three levels of security privileges that can be assigned to any user. They are: • • • • GUEST: Users are able to navigate most of the site, and view modem parameter settings. OPER: Users can monitor and control modem parameter settings, and change their own authentication passwords. ADMIN: At this highest access right, users can monitor and control modem parameter settings, change any user’s name and authentication password, and modify IP network settings. This setting has full access to the entire site. NO GROUP: Assigning this will block all access from the site. Listed in the table below are the factory default user names and corresponding default passwords and settings: USER ID Access Group Authentication Password Web User USER 1 USER 2 USER 3 GUEST OPER ADMIN guest oper admin guest oper admin All entries are case sensitive. Using the Front Panel display and arrow keys, scroll thru the System menu until the WEB sub menu is displayed. Enter into the WEB menu and the following Sub menus will appear (order may vary). 1. CONFIRMATION: When ENABLED, a change in the Web Interface will prompt a secondary window to be displayed asking “Do you want to proceed”. This will allow the user to either OK the change or cancel the change. When this feature is DISABLED, the command will be executed upon entering the command or parameter change. Commands pertaining to frequency and data rates cannot be overridden. The Confirmation command is located under PASSWORD SETUP/PREFERENCES. 2. USER 1: This will allow the operator to change the user name, assign the Access group, authorized password for “USER 1”. Upon entering the following fields will be displayed: a. ACCESS GROUP: This will allow the assignment of “No Group”, “ADMIN”, “OPER”, or GUEST to USER 1. b. AUTH PASSWORD: This will allow for the entry of the password for USER 1. c. USER RESET: Using this command will allow the factory defaults (as listed in the table above) to be restored to USER 1. This can be used in the event that USER 1 is locked out due to password restriction. 3. USER 2: This has the same menu structure as USER 1. 4. USER 3: This has the same menu structure as USER 1. Radyne’s Web configuration allows for the support of 3 user profiles. These are configured through the ‘PASSWORD/SETUP ACCESS section in the Web Browser.

Monitor and Control Web Page The top of the web page displays an alarm section reflecting the current front panel status of the modem. This block will be updated immediately whenever status is changed. The navigation scheme consists of gel tabs that correspond to the front panel top-level menu selections. When the mouse is dragged over a tab, it gets highlighted with a rollover effect and a sub-level of selections is revealed. These correspond to the front panel sub-menus. Below the menu gel tabs, the main menu section will reflect the current programmed control state. At the top of the page, breadcrumb location identifier reminds the user how the page is selected (Location Identifier). There is a simple navigation scheme that consists of gel tabs centralized on the main page. F-6 Appendix G. AUPC Operation G.1 Automatic Uplink Power Control (AUPC Operation) The modem has an optional built-in provision for Automatic Uplink Power Control, AUPC. AUPC is useful when operating power levels are affected by environmental changes in the atmosphere. AUPC attempts to adjust local power output to maintain a constant Eb/No at the receiver location. The modem supports three versions of AUPC. They include Radyne AUPC, EF AUPC and Near Side AUPC. Radyne AUPC and EF AUPC use satellite overhead to send messages between the local and remote ends of an SCPC link. The messaging is done with IBS 1/15 and EF AUPC Framing messages. G.1.1 Radyne AUPC In this case, Target Eb/No indicates the remote value the local unit wants to maintain by adjusting the local power level. Radyne AUPC can be set to operate on either or both directions of a link but always require a bi-directional channel. Enabling AUPC on one side of the link will activate AUPC on the distant end of the link. It is necessary that both the Modulator and Demodulator be set to the appropriate framing for AUPC options to be editable and for the AUPC function to operate properly. Examples of the basic Radyne AUPC Operations are described as follows: Assume that the two modems, one at each end of the link, are set to Radyne AUPC operation. Only one direction is discussed, but the same functions could be occurring in both directions simultaneously. Local Modem is transmitting to Remote modem under normal conditions and the Remote modem has a receive Eb/No of 7.5 dB. Local modem has been set to a Target Eb/No of 7.5 dB with an output power level of -15 dBm. It begins raining at Remote site and the Eb/No drops to –7.0 then –6.8 dB. Remote Modem is constantly sending update messages of its Eb/No to Local modem. When Local modem sees the drop in the remote Eb/No, it slowly begins to raise the output power, and will continue to adjust if the remote Eb/No continues to drop. As the rain increases in intensity, the remote Eb/No decreases but Local modem continues to increase its power level to compensate. When the rain diminishes, Local modem will see the remote Eb/No begin to increase. Local modem will lower its power level. The operation is therefore a feedback control loop with the added complication of a significant time delay. G-1 Universal Satellite Modem Revision 2 AUPC Operation G.1.2 EF AUPC In EF AUPC mode, the Target Eb/No indicates the local unit wants the remote unit to maintain a power level sufficient to provide the local Eb/No value. EF AUPC can be set to operate on either or both directions of a link but always require a bi-directional channel. Enabling AUPC on one side of the link will activate AUPC on the distant end of the link. It is necessary that both the Modulator and Demodulator be set to the appropriate framing for AUPC options to be editable and for the AUPC function to operate properly. Examples of the basic EF AUPC Operations are described as follows: Assume that the two modems, one at each end of the link, are set to AUPC operation. Only one direction is discussed, but the same functions could be occurring in both directions simultaneously. The local modem is transmitting to modem at a remote locale under normal conditions. The remote modem has a receive Eb/No of 7.5 dB. The local modem has been set with a Target Eb/No of 7.5 dB, and has a current power output of –15 dBm. It begins to rain at the local site, and the Eb/No drops to –7.0 then –6.8 dB. The local modem is constantly sending update messages of its Eb/No to the remote modem. When the remote modem sees the drop in the Eb/No, it slowly begins to raise it’s output power, and will continue to do so until the Target Eb/No is restored at the local site. When the rain diminishes, the local modem’s Eb/No will begin to increase. The remote modem will now lower its power level to restore the target value. The operation is therefore a feedback control loop with the added complication of a significant time delay. G.1.3 Near Side AUPC Near Side AUPC is a loop back system that adjusts the broadcast uplink signal when local conditions change. This is done by having the Near Side AUPC attempt to adjust the outbound power to compensate for local weather. The local receiver must be tuned and locked to the transmitter and then the internal Eb/No., is used for feedback. This creates a Tx-Satellite-Rx control loop. Near Side AUPC is primarily used for broadcast applications since the modem cannot expect to receive data from a distant location. Near Side AUPC can be utilized with any satellite framing or Network mode. There are safeguards built into the AUPC System. First, the modulator has two parameters, which allow control of the maximum and minimum output power Levels. Second, a nominal, or default, power level is specified which takes effect if the receive signal or messaging is lost. This nominal power should be set to a level high enough to re-establish communications regardless of rain fade. EF AUPC, also provides some control over the rate of power change; while the Radyne and Near Side AUPC use a optimized rate for rain fade compensation. G-2 Universal Satellite Modem Revision 2 AUPC Operation The AUPC Menu Functions and their descriptions are shown on Table G-1 ands G-2. Table G-1.

Revision 2 Drop and Insert (D&I) Drop and Insert (D&I) H.1 Drop and Insert (D&I) The Drop and Insert (D&I) function provides an interface between a full T1 or E1 Trunk whose framing is specified in CCITT G.704 and a fractional Nx64 Kbps Satellite Channel. The Drop and Insert functionality conforms to IBS, small IDR, and Radyne Proprietary Efficient D&I Framing Structures. For information pertaining to Radyne proprietary Efficient Drop and Insert function, refer to Appendix I. The Drop function allows the user to select the terrestrial T1 or E1 timeslots that are to be dropped off for transmission over the link in the specified satellite channels. The Insert function allows the user to select the T1 or E1 timeslots into which the received satellite channels are to be inserted. The two functions are completely independent allowing maximum flexibility in choosing configurations. The four-port G.703 Interface allows one or more modems to be looped together using the same T1 or E1 trunk. The Transmit Data Trunk is brought into the modem via the Send Data In (SDI) Port. From there, the TX Baseband Processor extracts the selected timeslots from the G.704 Frame and prepares them for transmission. The original trunk data is sent out of the modem unaltered via the Send Data Out (SDO) Port. The Receive Data Trunk is brought into the modem via the Insert Data In (IDI) Port. The data is buffered inside the modem and the RX Baseband Processor inserts satellite data into the selected timeslots in the G.704 Frame. The modified terrestrial trunk is then output via the Receive Data Out (RDO) Port. Figure H-1 shows two modems looped together. This configuration could be simplified to just use one modem, or extended to use more than two modems. Figure H-2 shows an alternative method of looping where all of the drop (transmit) data is processed prior to performing any insert (receive) processing. In both configurations, the terrestrial trunk is providing the timing for the satellite transmission and for the terrestrial receive.

Looped Modems with Separate D&I Trunks H-2 Universal Satellite Modem Revision 2 Drop and Insert (D&I) H.1.1 Drop Only When Drop is enabled and Insert is disabled, the unit performs a drop-only function. Framed E1 or T1 Data is input via the Send Data In Port, the selected timeslots are dropped into the IBS frame structure, and the unaltered terrestrial data is output via the Send Data Out Port (refer to Figure H-3). Figure H-3. Drop Only H.1.2 Insert Only When Insert is enabled and Drop is disabled, the unit performs an insert-only function. If framed terrestrial E1 or T1 Data is available, it should be input via the Insert Data In Port. The Terrestrial Data is buffered inside the Modem. The RX Baseband Processor inserts satellite data into the selected timeslots in the G.704 Frame and the modified terrestrial data is then output via the Receive Data Out Port (refer to Figure H-4). If framed terrestrial data is not available, selection of the Internal T1/E1 frame source will cause the modem to generate the required G.704 Frame. The Satellite Data will be inserted into the selected timeslots, and the resulting terrestrial data will be output via the Receive Data Out Port. Any non-inserted timeslots in the G.704 Frame will be filled with the appropriate Idle Code (refer to Figure H-5). Figure H-4. Insert Only with Eternal Frame Source H-3 Universal Satellite Modem Revision 2 Drop and Insert (D&I) Figure H-5. Insert Only with Internal Frame Source H.1.3 Mode Selection D&I can be easily configured to support several commonly used terrestrial data formats. For E1 Data, the user can choose between PCM-30, PCM-30C, PCM-31 and PCM-31C. For T1 Data, the user can choose between T1-D4, T1-ESF, and SLC-96. The following paragraphs provide more information on the various mode selection capabilities. H.1.3.1 PCM-30 The PCM-30 Mode of Operation supports an E1 Interface with Multiframe Alignment (MFAS) and Channel Associated Signaling (CAS). The user may independently program n timeslots to drop and n timeslots to insert where n = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30. In addition to the selected drop timeslots, the Transmit Function also extracts the appropriate ABCD signaling bits from terrestrial timeslot 16 for transmission in IBS Frame as required. Conversely, the Receive Function extracts received ABCD signaling bits from the IBS Frame and inserts them in timeslot 16 of the appropriate terrestrial frame. This transmission and reception of ABCD signaling based upon the drop and insert timeslots is performed automatically and is transparent to the user. In PCM-30 mode, the user may not select timeslot 16 as a Drop or Insert Timeslot. H.1.3.2 PCM-30C The PCM-30C Mode of Operation supports an E1 Interface with Multiframe Alignment (MFAS) and Channel Associated Signaling (CAS). In addition, the Drop function verifies the received terrestrial CRC checksum and the Insert function calculates the required CRC checksum. The user may independently program n timeslots to drop and n timeslots to insert where n = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30. In addition to the selected Drop timeslots, the Transmit Function also extracts the appropriate ABCD signaling bits from terrestrial timeslot 16 for transmission in IBS Frame as required. Conversely, the Receive Function extracts received ABCD signaling bits from the IBS frame and inserts them in timeslot 16 of the appropriate terrestrial frame. This transmission and reception of ABCD signaling based upon the Drop and Insert timeslots is performed automatically and is transparent to the user. In PCM-30C Mode, the user may not select timeslot 16 as a Drop or Insert Timeslot. H.1.3.3 PCM-31 The PCM-31 Mode of Operation supports an E1 Interface with no Multiframe Alignment (MFAS) or Channel Associated Signaling (CAS). The user may independently program n timeslots to drop and n timeslots to insert where n = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30. Because there is no implied ABCD signaling, the user is free to select timeslot 16 as a Drop or Insert Timeslot. H-4 Universal Satellite Modem Revision 2 Drop and Insert (D&I) H.1.3.4 PCM-31C The PCM-31C Mode of Operation supports an E1 Interface with no Multiframe Alignment (MFAS) or Channel Associated Signaling (CAS). In addition, the Drop Function verifies the received terrestrial CRC checksum and the Insert Function calculates the required CRC checksum. The user may independently program ‘n’ timeslots to drop and ‘n’ timeslots to insert where ‘n’ = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30. Because there is no implied ABCD signaling, the user is free to select timeslot 16 as a Drop or Insert Timeslot. H.1.3.5 T1-D4/T1-D4-S The T1-D4 Mode of Operation supports a T1 Interface with 12 frames per multiframe. The user may independently program n timeslots to drop and n timeslots to insert where n = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30. Robbed Bit Signaling (RBS) is handled without any need for operator intervention and is transparent to the user. H.1.3.6 T1-ESF/T1-ESF-S The T1-ESF Mode of Operation supports a T1 Interface with 24 frames per multiframe. The CRC-6 checksum is automatically checked by the Drop Function and generated by the Insert Function and placed in the appropriate F-bit positions in the terrestrial multiframe. The user may independently program n timeslots to drop, and n timeslots to insert, where n = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30. Robbed Bit Signaling (RBS) is handled without any need for operator intervention and is transparent to the user. H.1.4 Multidestinational Systems Because the Drop and Insert Functions are completely independent, so multi-destinational communications are easily supported.. Figure H-6 illustrates a Multi-destinational System with one Hub site and three remote sites. At the Hub site, thirty channels are being transmitted to all three remote sites and a fractional set of channels is being received from each remote site. At the other end of the link, each remote site is transmitting a fractional E1 to the Hub site as well as receiving all 30 channels from the Hub site. It also identifies those channels intended for it, and inserts them into the terrestrial data stream. H-5 Universal Satellite Modem Revision 2 Drop and Insert (D&I) H.1.5 Drop and Insert Mapping The following displays under Interface D&I Setup (both Tx and Rx), are editing displays only: SATCh TS Enter to Edit Any changes made in these displays are made on the screen, but are not entered into the modem. Once these menus are configured, the Mapping Menu must be used to actually enter the settings into the modem. Figure H-6. Multidestinational Communications H-6 Universal Satellite Modem Revision 2 Drop and Insert (D&I) Example : For a modem w/ Drop & Insert enabled at a data rate of 256 (with timeslots assigned 1 - 1, 2 - 2, etc.). At a data rate of 256, the modem will allow 4 channels to assign timeslots. Under the Tx Menu, assign the timeslots that are to be used to the 4 channels. CH1 is assigned to TS1 (Timeslot #1), CH2 to TS 2, CH3 to TS3 and CH4 to TS4, <ENTER> must be depressed after assigning each individual TS. Once the timeslots are assigned to the channels, use the Left or Right Arrow Key to scroll to the Mapping Menu. This menu will appear in the following way: Map ******* Copy ******* This is the menu where the channel assignments are actually entered into the modem. To do this, perform the following steps: For the Transmit Side: 1. Push <ENTER> to get the flashing cursor. 2. Use the Up Arrow Key to make the left portion of the display read “TX EDIT”. 3. Use the Right or Left Arrow Keys to switch the flashing cursor to the right portion of the display. 4. Use the Up or Down Arrow Key to until the right hand portion displays “TX ACTIVE”. 5. The mapping display should now look like this: Map Copy TX EDIT > TX ACTIVE 6. Push <ENTER> to enter this command. This tells the modem to configure to the settings that were assigned in the Channel/Timeslot display. For the Receive Side: 1. With Rx Side Channels configured as follows: CH1 to TS1, CH2 to TS2, CH3 to TS3, and CH4 to TS4. 2. After the timeslots are assigned properly, scroll to the Mapping Menu and use the above procedure to enter the settings into the modem. 3. Set the display to read: Map Copy RX EDIT > RX ACTIVE 4. Press <ENTER> to enter the settings into the modem. H-7 Universal Satellite Modem Revision 2 Drop and Insert (D&I) To View the current Timeslot Assignment: 1. If there is a question of the channels not being entered properly, the Mapping Menu may be used to see how the channels/timeslots are configured in the modem. 2. Use <ENTER> and the Arrow Keys to make the mapping menu read (for the Tx Side): Map Copy TX ACTIVE > TX EDIT 3. Press <ENTER>. The modem has now copied the current Tx Settings to the Tx Channel/Timeslot Display. 4. For the Rx Side: Map Copy RX ACTIVE > RX EDIT 5. Press <ENTER>. The modem has now copied the current Rx Settings to the Rx Channel/Timeslot display ). It is not mandatory to assign timeslots in sequential order, although the lowest timeslot must be entered in the lowest channel. For example: timeslots may be assigned 1 - 2, 2 - 5, etc. but not 1 - 5, 2 - 2. H.2 Configuring the Modem for Drop and Insert Several dependencies exist when configuring the modem for Drop and Insert (D&I). The following paragraphs explain these dependencies and provide the user with the information required to ensure smooth transition into D&I and to minimize the potential impact of these dependencies. H.2.1 Data Rate Data Rate affects the Drop and Insert function in the following ways: • It determines the number of Satellite Channels that will be displayed in the Edit Maps. • It contributes to the Operational Mode selection process. Trying to change the Operational Mode to D&I when a data rate is not set to a valid D&I rate will result in the error message ‘INVALID DATA RATE,’ and the mode change will not be allowed. • It contributes to the Terrestrial Framing Mode selection process. Trying to select a T1-type Drop Mode such as T1-ESF with the mod data rate set to 1920000 bps (a valid E1 D&I rate but not a valid T1 rate) will result in the error message ‘INVALID DROP MODE’ and the selection will not be allowed. Trying to select a T1 type Insert Mode such as T1-D4 with the demod data rate set to 1920000 bps will result in the error message INVALID INSERT MODE and the selection will not be allowed. H-8 Universal Satellite Modem Revision 2 Drop and Insert (D&I) • Once D&I Mode has been selected, trying to change the data rate to something other than another valid D&I data rate will result in the error message ‘RATE OUT OF BOUNDS’ and the change will not be allowed. • Once D&I Mode has been selected with a T1 Terrestrial Framing Mode, attempting to change the data rate to 1920000 will result in the error message ‘RATE OUT OF BOUNDS’ and the change will not be allowed. Therefore, the data rate should be entered as the first step in configuring the modem for D&I. The Mod Data Rate should be set according to the number of timeslots to be dropped and the Demod Data Rate should be set according to the number of timeslots to be inserted. The following table gives the allowable D&I data rates based on the number of slots (n) to be dropped or inserted. n = 1, data rate = 64000 n = 2, data rate = 128000 n = 3, data rate = 192000 n = 4, data rate = 256000 n = 5, data rate = 320000 n = 6, data rate = 384000 n = 8, data rate = 512000 n = 10, data rate = 640000 n = 12, data rate = 768000 n = 15, data rate = 960000 n = 16, data rate = 1024000 n = 20, data rate = 1280000 n = 24, data rate = 1536000 n = 30, data rate = 1920000 (valid with E1 Interface only) H.2.2 Operational Network Specification The Network Specification of the Modem often determines which additional menus and displays are available for use by the operator. The D&I Mode-specific menus will not be displayed unless the Network Specification of the modem is set to D&I. Therefore, the second step in configuring the modem should be to set the Network Specification to D&I. At this point, the D&I specific menus in the Interface section will become available and will remain available until the Network Specification of the modem is changed to something other than D&I. When the Network Specification is changed to something other than D&I, the D&I specific menus will automatically disappear. H.2.3 Terrestrial Framing - Drop Mode/Insert Mode The Drop Mode Selection and the Insert Mode Selection identify the Terrestrial Data-Framing Format. As previously mentioned, their selection is influenced by the Modulator and Demodulator Data Rates, and trying to select a T1 Type Framing Format with a data rate of 1920000 bps will result in an error message. In turn, the selection of the terrestrial framing formats influences the satellite channel to terrestrial timeslot mappings in the following manner: The selection of T1-D4, T1-ESF, or SLC-96 type terrestrial framing format limits the terrestrial timeslots to values from 1 - 24. The selection of PCM-30 or PCM-30C type terrestrial framing limits the terrestrial timeslots to values from 1 - 15, 17 - 31. In these modes, terrestrial timeslot 16 is reserved for ABCD signaling and may not be dropped or inserted. H-9 Universal Satellite Modem Revision 2 Drop and Insert (D&I) The selection of PCM-31 or PCM-31C type terrestrial framing limits the terrestrial timeslots to values from 1 - 31. Therefore, the terrestrial framing format should be identified via the Drop Mode and Insert Mode entries prior to editing the Drop or Insert satellite channel to terrestrial timeslot maps. H.2.3.1 Insert Terrestrial Frame Source The Insert Terrestrial Frame Source selection tells the Modem from where the Insert Terrestrial Frame is coming. External: Indicates that the terrestrial frame is to be input via the Insert Data In Port. Internal: Indicates that the modem needs to generate the terrestrial frame and that all non-inserted timeslots need to be filled with the appropriate idle code based upon the terrestrial framing (T1 or E1). The selection of the Insert Terrestrial Frame Source also influences the Buffer Clock selection in the following manner: When the Insert Terrestrial Frame Source selection is set to External, the received satellite data will be clocked out of the Doppler Buffer based upon the clock recovered from the insert data input. Therefore, the Buffer Clock selection will automatically be set to External and cannot be modified. Attempts to select a different buffer clock will result in the error message INVALID BUFFER CLOCK and the selection will not be allowed. When the Insert Terrestrial Frame Source selection is set to Internal, the operator needs to specify how data should be clocked out of the Doppler Buffer. In this case, the operator will be able to select SCTE, SCT, RX SAT, or EXT EXC as the source for the Buffer Clock. Therefore, the Insert Terrestrial Frame Source selection should be made prior to attempting to change the Buffer Clock. In most instances, the Insert Terrestrial Frame Source selection will be set to External and the Buffer Clock will automatically be set to External. H.2.4 D&I Sample Configurations and D&I Clock Setup Options The following are several examples of how to configure the modem for D&I. Also, refer to Figures 3-14 through 317 for the D&I Clocking Setup Options Available. Example 1: Drop 512 Kbps from a T1 trunk, 3/4 Rate Viterbi Insert 512 Kbps into a T1 trunk, 3/4 Rate Viterbi Drop 512 Kbps from a T1 trunk, 3/4 Rate Viterbi Under Interface: Under TX Setup: Set Tx Type according to your hardware configuration (example: G703BT1B8ZS) Set Tx Clock = SCTE Under Tx D&I: Set Drop Mode = T1-D4 Use SATCh TS edit capability to define desired mapping of Satellite Channels to drop Terrestrial Slots Use Map Copy to copy Tx Edit to Tx Active Under Modulator: Under Mod Data: Set Data Rate = 512000 Set Conv Enc = 3/4 Rate VIT Under Modulator: Set Network Spec. = Drop & Insert Under Interface: H-10 Universal Satellite Modem Revision 2 Drop and Insert (D&I) Under TX Setup: Set Tx Type according to your hardware configuration (example: G703BT1B8ZS) Set Tx Clock = SCTE Under Tx D&I: Set Drop Mode = T1-D4 Use SATCh TS edit capability to define desired mapping of Satellite Channels to drop Terrestrial Slots Use Map Copy to copy Tx Edit to Tx Active Under Modulator: Under Mod IF: Set Frequency to desired value Turn IF Output Power On Under Demodulator: Under Demod Data: Set Data Rate = 512000 Set Conv Enc = 3/4 Rate VIT Under Interface: Under RX Setup: Set Rx Type according to your hardware configuration Set Buff Size to desired depth Under Rx D&I: Set Insert Mode = T1-D4 Set T1 E1 Frm Src = External Use SATCh TS edit capability to define proper mapping of Satellite Channels to insert Terrestrial Slots Use Map Copy to copy Rx Edit to Rx Active Under Demodulator: Under Demod IF: Set Frequency to desired value Under Demodulator: Set Network Spec. = Drop & Insert Example 2: Multidestinational Remote Site Programming Drop 512 Kbps from a T1 trunk, 3/4 Rate Viterbi. Extract 512 Kbps from a 1536 Kbps carrier and insert into a T1 trunk, 3/4 Rate Viterbi. Drop 512 Kbps from a T1 trunk, 3/4 Rate Viterbi Configuration setup is exactly as previously shown in Example 1. Extract 512 Kbps from a 1536 Kbps carrier and insert into a T1 trunk, 3/4 Rate Viterbi Under Interface: Under RX Setup: Set Rx Type according to your hardware configuration Set Buff Size to desired depth Under Rx D&I: Set Insert Mode = T1-D4 Set T1 E1 Frm Src = External Use SATCh TS edit capability to define proper mapping of Satellite Channels to insert Terrestrial Slots For Satellite Channels that are not to be inserted, enter “NI” (No Insert) for the Terrestrial Slot H-11 Universal Satellite Modem Revision 2 Drop and Insert (D&I) Use Map Copy to copy Rx Edit to Rx Active Under Demodulator: Under Demod Data: Set Data Rate = 1536000 Set Conv Enc = 3/4 Rate VIT Under Demodulator: Set Network Spec. = Drop & Insert Under Demodulator: Under Demod IF: Set Frequency to desired value.

Single Trunk H-12 Universal Satellite Modem Revision 2 Drop and Insert (D&I) Figure H-9. Rx Only With Trunk Figure H-10. Rx Only No Trunk H-13 Universal Satellite Modem Revision 2 Drop and Insert (D&I) H.3 D&I Maps and Map Editing The Drop and Insert multiplexer is programmed by loading it with a transmit and receive map. Maps always contain 30 entries, although, only the first “n” entries are relevant (see Table 4-5). The modem includes provisions to copy, change, and store the D&I transmit and receive maps directly from the Front Panel or via the remote M&C link. These maps are tables that are used to define and configure the D&I functions. Each map contains up to 30 entries, which are enough to define the channel assignments for a T1 (24 channel) or E1 (30 channel) frame structure. Maps that are created are stored in non-volatile battery backed-up memory within the modem and remain unchanged after a power-down. Table H-1. D&I Multiplexer Map Locations Used D&I Multiplexer Map Locations Used Data Rate (Kbps) Map Locations Used (n = 1, 2,4,8,16,24,30) 64 1 128 1-2 256 1-4 384 1-6 512 1-8 768 1-12 1024 1-16 1536 1-24 1920 1-30 It is important to understand that each map contains up to 30 usable entries. In many cases a smaller number of entries will be relevant, except when the data rate is 1920 Kbps, in which case 30 entries will used by the multiplexer. To determine the number of relevant entries, divide the data rate by 64 Kbps. For example: At 384 Kbps, 384/64 = 6 entries. Therefore, in this case only the first six entries of the map would be relevant. The Modem is equipped with eight permanently stored default maps, which are designated ROM 1 through ROM 8. The user may also define, modify, and save an additional eight maps which are designated USER 1 through USER 8. ROM maps are read-only and may not be modified (refer to Table H-2). H-14 Universal Satellite Modem Revision 2 Drop and Insert (D&I) ROM Map Table H-2. D&I ROM Maps T1/E1 Time Slot # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 3 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 4 1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 4 5 6 5 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 1 2 3 4 5 6 6 1 2 3 4 5 6 7 8 9 10 11 12 1 2 3 4 5 6 7 8 9 10 11 12 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Since the D&I Functions are separate and distinct, two separate maps must be configured at the start of the D&I Multiplexer Operation. These are the Tx (transmit) Active Map for Drop Mapping and the Rx (receive) Active Map for Insert Mapping. The number of entries in each map is determined by the data rates selected. Each map entry consists of an IBS Time Slot assignment and the Terrestrial (T1 or E1) Channel Number to which it is assigned. Drop Mapping and Insert Mapping are completely separate and independent. The map that is actually used for the Drop Function is the Tx Active Map; the map that is actually used for the Insert function is the Rx Active Map. Two additional maps exist: the Tx Edit Map and the Rx Edit Map. The Edit Maps are the buffer areas that are used when creating or modifying a map through the modem’s LCD; when editing is complete, the appropriate map should be copied to the Active Map. Any map may be copied to any other map with the exception of the ROM maps. These maps may only be the source of the data used to create a User, Edit, or Active Map. Maps can be created in the map editor and stored as “User Maps”. New “Active Maps” can be downloaded during Modem Operation but this will result in a temporary disruption of service on the terrestrial line or the Satellite transmission. The following paragraphs give examples of typical configurations that could use the ROM Maps as templates. The ROM Map used would have to be first copied to the appropriate Active Transmit (Drop) and/or Active Receive (Insert) Map(s) before it could be used. To use a modification of a ROM Map, the ROM Map must first be copied to the appropriate Edit Map, then modified, and then copied to the appropriate Active Map. The mapping of channels to time slots is arbitrary; it is not necessary to map CH1 to TS1, CH2 to TS2, etc. The channel to the time slot mapping may be in any order within the constraints of the number of available channels. For example, ROM Map 1 could be used as the template for an Active Transmit (Drop) Map within a modulator configured for 64 Kbps operation. Only the first time slot of the T1 or E1 frame would be dropped into the modulator transmit path. The Drop Multiplexer would know to look only at the first entry in the Active Transmit H-15 Universal Satellite Modem Revision 2 Drop and Insert (D&I) table and would ignore the other 29 entries. If the map contained an “8” in its first entry, the eighth channel of the T1/E1 frame would be sent to the modulator. ROM Map 2 could be used as the template for an Active Receive (Insert) Map within a demodulator configured for 128 Kbps operation. The demodulated data in the receive path would be inserted into the first two time slots of the T1 or E1 frame. The Insert Multiplexer would know to look only at the first two entries in the Active Receive table and would ignore the other 28 entries. If the first two entries were modified to contain a 27 and 28, the data would be inserted into the 27th and 28th time slots of the E1 frame. ROM Map 3 could be used as the template for an Active Transmit (Drop) Map with a modulator and/or demodulator configured for 256 Kbps operation. The T1 or E1 Data in the transmit path or the demodulated data in the receive path would be dropped from and/or inserted into the first four time slots of the T1 or E1 frame. The Multiplexer would know to look only at the first 4 entries in the Active map(s) and would ignore the other 26 entries. ROM Map 4 could be used as the template for an Active Transmit (Drop) or Active Receive (Insert) Map with a modulator and/or demodulator configured for 384 Kbps operation. The T1 or E1 Data in the transmit path or the demodulated data in the receive path would be dropped from and/or inserted into the first six time slots of the T1 or E1 frame. The Insert Multiplexer would know to look only at the first six entries in the Active map(s) and would ignore the other 24 entries. To Drop the last six channels of a T1 frame into a modulator transmit path, the first six entries of the Active Transmit map should contain 19, 20, 21, 22, 23, and 24. ROM Map 5 could be used as the template for an Active Transmit (Drop) and/or Active Receive (Insert) Map with a modulator and/or demodulator configured for 512 Kbps operation. The T1 or E1 Data in the transmit path or the demodulated data in the receive path would be dropped from and or inserted into the first eight time slots of the T1 or E1 frame. The Multiplexer would know to look only at the first eight entries in the Active map(s) and would ignore the other 22 entries. To insert data received from a demodulator into channels 17 through 24 of an E1 frame, the first eight entries of the Active Receive map should contain 17, 18, 19, 20, 21, 22, 23, and 24. ROM Map 6 could be used as the template for an Active Transmit (Drop) and/or Active Receive (Insert) Map with a modulator and/or demodulator configured for 768 Kbps operation. The T1 or E1 Data in the transmit path or the demodulated data in the receive path would be dropped from and or inserted into the first 12 time slots of the T1 or E1 frame. The Multiplexer would know to look only at the first 12 entries in the Active map(s) and would ignore the other 18 entries. To insert data received from a demodulator into channels 3 through 14 of an E1 frame, the first 12 entries of the Active Receive map should contain 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14. ROM Map 7 could be used as the template for an Active Transmit (Drop) and/or Active Receive (Insert) Map with a modulator and/or demodulator configured for 1920 Kbps operation. This would be used with E1 frames where time slot 16 is not used for the multiframe alignment signal and therefore channels 1 through 30 are mapped directly with time slots 1 through 30. ROM Map 7 could also be used as the template for an Active Transmit (Drop) and/or Active Receive (Insert) Map with a modulator and/or demodulator configured for 1024 Kbps operation. This would be used with T1 or E1 frames where channels 1 through 16 are mapped into time slots 1 through 16 (in any order). Map slots 17 through 30 would be ignored. ROM Map 7 could also be used as the template for an Active Transmit (Drop) and/or Active Receive (Insert) Map with a modulator and/or demodulator configured for 1536 Kbps operation. This would be used with T1 frames where channels 1 through 24 are mapped into time slots 1 through 24 (in any order). Map slots 25 through 30 would be ignored. ROM Map 8 could also be used as the template for an Active Transmit (Drop) and/or Active Receive (Insert) Map with a modulator and/or demodulator configured for 1920 Kbps operation. However, this mapping would be relevant with E1 frames where time slot 16 is used for the multiframe alignment signal and therefore channels 1 through 30 are mapped to time slots 1 through 16 and 17 through 31. H-16 Appendix I. I.1 Efficient Drop & Insert Introduction The following paragraphs describe the menu structure and procedure for configuring a modem for Efficient Drop & Insert Mode. I.2 Prerequisite In order for a modem to be configured for Efficient Drop & Insert, the modem must have a G.703 Interface card installed and Drop & Insert option must be enabled. If the modem does not have the required hardware and/or feature set enabled, contact your Radyne sales representative to order the appropriate hardware and/or feature set upgrade. If the modem has the appropriate hardware, but the software revision is prior to AY, you will need to download the latest modem firmware from the Radyne FTP website. The following menus illustrate how to determine whether or not the modem has the required hardware and feature set options.

In addition, the selection and operation of Enhanced Async and AUPC are identical to their closed network IBS counterparts. For more information on these selections, refer to the appropriate section of the User’s manual. The following menu selections are utilized for controlling the additional functionality available with efficient Drop and Insert: MODULATOR or DEMODULATOR NETWORK SPEC CLOSED NET Efficient Drop & Insert is a Closed Network selection SAT FRAMING EFFICIENT D&I DATA DATA RATE (bps) N x 64000 The satellite frame type is Efficient Drop & Insert The data rate can be set to any N x 64 kbps rate based on the desired number of drop or insert slots. The following values of N are allowed based on the terrestrial interface and terrestrial framing types shown T1 E1 E1 SCRAMBLER CTRL DISABLED Any framing Any PCM31 Any PCM30 Any N from 1 to 24 Any N from 1 to 31 Any N from 1 to 30 as TS 16 is automatically transmitted The Efficient Drop & Insert mode utilizes a frame synchronous energy dispersal technique that is always on, thus there is no need for any additional scrambling INBAND RATE 150 300 600 This menu is available when enhanced async is enabled. This field allows the operator to select a desired Earth Station to Earth Station in-band rate. This allows the user to optimize the InBand 1200 Rate based on the amount of traffic that will pass over the. 2400 satellite. In most cases, this should be set to the same rate or 4800 higher than the TX & RX Async/ ES port baud rate. When this 9600 set lower than the ES port baud rate, the user must insure 19200 that the actual ES to ES transmission rate does not exceed the In-Band Rate, otherwise characters will be dropped. rate is I.3.1 Calculating the Required Satellite Bandwidth In order to calculate the satellite bandwidth (i.e. the symbol rate), we must first calculate the Efficient D&I Rate (i.e. the data rate plus the overhead required for Efficient Drop & Insert). From there, the calculation of the required satellite bandwidth is identical to all other modes of operation and simply takes into account modulation type and forward error correction. In this section, we will cover the calculation of the basic Efficient D&I Rate, as well as, the two cases that alter the basic rate. I-2 Universal Satellite Modem Efficient Drop & Insert Revision 2 I.3.2 Calculating the Basic Efficient D&I Rate When E1 signaling is not required (all T1 and PCM31 cases) and Enhanced Async is not enabled (the Earth Station to Earth Station link is the standard ES-ES), the Efficient D&I Rate for N timeslots is as follows: Efficient D&I Rate = Data Rate + (N * 250 bps) In other words, the basic Efficient Drop & Insert Rate only requires 250 bps of overhead per slot, while at the same time providing all of the functionality found in the Drop & Insert open network standard plus Automatic Uplink Power Control. By comparison, the Drop & Insert open network standard requires 4267 bps per slot, so by utilizing Efficient Drop and Insert, Radyne customers can realize a bandwidth savings of over 4000 bps per slot. I.3.3 Calculating the Efficient D&I Rate with E1 Signaling When E1 signaling is enabled (PCM-30, PCM30C), an additional 2000 bps per slot are required to carry the E1 signaling. So the Efficient D&I Rate for N timeslots is: Efficient D&I Rate increase = N * 2000 bps With the Drop & Insert open network standard requiring 4267 bps per slot, Efficient Drop and Insert provides a bandwidth savings of over 2000 bps per slot when E1 signaling is required. I.3.4 Calculating the Efficient D&I Rate with Enhanced Asynchronous Overhead The amount of overhead required to carry the Enhanced Async is driven by the in-band baud rate. The calculation is a two step process involving the in-band baud rate and the number of slots as follows: X = Truncation of (In-Band Baud Rate / (N * 125)) Efficient D&I Rate increase = X * N * 125 bps Because of the truncation, this increase in bandwidth is guaranteed to be less than the baud rate itself. Summary and Examples: The following examples further illustrate how to calculate the Efficient D&I rate which can be summarized for N timeslots as: Efficient D&I Rate = Data Rate + (N * 250 bps) With E1 signaling add N * 2000 bps With Enhanced Async add (Truncation (In-Band Baud / (N * 125))) * (N * 125) bps Example 1a: 5 Drop Slots with T1-D4 framing, standard ES to ES overhead For 5 Drop Slots, the Data Rate would be 5 * 64000 or 320000 bps I-3 Universal Satellite Modem Efficient Drop & Insert Revision 2 The Efficient D&I Rate would be 320000 + (5 * 250) bps = 321250 bps The Drop & Insert Open Network rate is over 20,000 bps higher at 341333 bps. Example 1b: Change to E1-PCM30 framing (E1 Signaling), standard ES to ES overhead Add 5 * 2000 bps to our previous calculation gives 331250 bps Still saving over 10,000 bps compared to the open network standard. Example 1c: Change to Enhanced Async with In-Band Baud Rate of 1200 X = Truncation of (1200 / (5 * 125) X = Truncation of (1.92) X=1 Add 1 * 5 * 125 bps to our previous calculation gives 331875 bps An increase of 625 bps to carry 1200 baud Example 2a: 10 Drop Slots with T1-D4 framing, standard ES to ES overhead For 10 Drop Slots, the Data Rate would be 10 * 64000 or 640000 bps The Efficient D&I Rate would be 640000 + (10 * 250) bps = 642500 bps The Drop & Insert Open Network rate is over 40,000 bps higher at 682667 bps. Example 2b: Change to E1-PCM30 framing (E1 Signaling), standard ES to ES overhead Add 10 * 2000 bps to our previous calculation gives 662500 bps Still saving over 20,000 bps compared to the Drop & Insert open network standard. Example 2c: Change to Enhanced Async with In-Band Baud Rate of 1200 X = Truncation of (1200 / (10 * 125) X = Truncation of (0.96) X=0 The rate stays at the previous value of 662500 With 10 slots, there is no increase required to carry 1200 baud Enhanced Async. It is passed transparently in the Efficient Drop & Insert overhead. I-4 Appendix J.
